Does it say its confirmed on you history? Or have you yourself just confirmed it?
I have waited up to 12 hours for deposits that i have confirmed, but were still pending, i think thats normal. At some point it will arrive. Just make sure you do not cancel the payment on dgex while its pending, if you do so, you will have to wait a very long time to get it back.
I dont have any experience with payments that are confirmed but do not show up though. In that case i would consider contacting dgex, after waiting maybe like another 4 hours.
